## Understanding Lock Types and Terminology
Before diving into specific choices, it’s helpful to understand common terms and lock types:
* **Keyed Entry Knobs/Levers:** These are the most common locks for exterior doors. They feature a key cylinder on the outside and a locking mechanism (button or turn-piece) on the inside.
* **Deadbolts:** Considered more secure than keyed entry knobs, deadbolts extend a solid metal bolt into the door frame, making them resistant to forced entry. They are often used in conjunction with a keyed entry knob.
* **Passage Locks:** These are interior locks with no locking mechanism, used for doors that require no privacy, such as closets or hallways.
* **Privacy Locks:** These interior locks have a locking mechanism on one side (usually a push-button or thumb-turn) and a small hole or slot on the exterior that can be used to unlock the door in emergencies. They are ideal for bathrooms and bedrooms.
* **Dummy Locks:** These are non-locking hardware pieces, often used for aesthetic purposes on doors that don’t require latching, such as closet doors.
### Keying Options Explained
* **Keyed Alike:** Multiple locks can be opened with the same key. This is convenient for properties with several doors.
* **Keyed Different:** Each lock requires a unique key. This offers greater security as one lost key won’t compromise all your locks.
* **Master Keyed:** A master key can open all locks in a set, while each lock also has its own unique key. This is common in commercial settings or large homes.
A standard door handle lock mechanism typically consists of a latch that retracts when the handle is turned and a bolt that secures the door when locked. For keyed locks, a cylinder Tumbler mechanism is used, where specific key cuts align pins to allow the cylinder to turn.
## Factors to Consider When Choosing
### Security Needs
The primary function of a door handle lock is security. For exterior doors, especially the main entry points of your home, prioritize high-security locks. Look for locks with:
* **ANSI/BHMA Grade Ratings:** The American National Standards Institute (ANSI) and the Builders Hardware Manufacturers Association (BHMA) grade locks on a scale of 1 to 3, with Grade 1 being the highest security and durability.
* **Pick and Bump Resistance:** Advanced lock cylinders are designed to resist common lock-picking and bumping techniques.
* **Solid Bolt Construction:** A solid, hardened steel bolt is more resistant to cutting and prying than a hollow one.
### Material and Durability
The material of the lock directly impacts its lifespan and resistance to wear and tear. Common materials include:
* **Brass:** Durable and resistant to corrosion, brass is a popular choice for locks. It can be plated with various finishes.
* **Stainless Steel:** Offers excellent corrosion resistance and strength, making it suitable for both interior and exterior use.
* **Zinc Alloy:** A more affordable option that can be durable, but may be more susceptible to corrosion than brass or stainless steel over time.
* **Bronze:** Offers a classic look and good durability, often used in high-end applications.
### Aesthetics and Finish
Door handle locks are also a significant design element. The finish you choose should complement your home’s overall style and the door itself. Popular finishes include:
* **Satin Nickel/Brushed Nickel:** A modern, versatile finish that hides fingerprints well.
* **Polished Brass:** A classic, warm finish that can add a touch of elegance.
* **Oil-Rubbed Bronze:** Offers a rustic, antique look.
* **Matte Black:** A contemporary and bold choice that is increasingly popular.
* **Polished Chrome:** A sleek, shiny finish that is highly durable.
### Functionality and Ease of Use
Consider how the lock will be used daily.
* **Levers vs. Knobs:** Levers are often easier to operate, especially for individuals with limited hand strength, children, or when carrying items.
* **Smart Locks:** For added convenience and enhanced security features, consider smart locks that can be controlled via smartphone apps, offer keyless entry, and integrate with smart home systems.
The deadbolt is a crucial component of home security. Its effectiveness lies in its throw bolt, which extends at least one inch into the door frame’s strike plate. A properly installed deadbolt, combined with a reinforced door frame, can significantly deter forced entry.
## Installation and Maintenance
Proper installation is key to a lock’s performance and security. Most modern locks are designed for straightforward installation and come with detailed instructions. However, if you are unsure, it is always best to consult a professional locksmith. Regular maintenance, such as lubricating the lock mechanism occasionally, can help ensure smooth operation and longevity.
### Tips for Installation:
* Ensure the door and frame are properly aligned.
* Use the correct drill bit sizes for pre-drilled holes.
* Tighten screws securely but avoid over-tightening, which can strip the threads.
* Test the lock thoroughly after installation.
